Application led .Tune 6, 1916. Serial No. 102,015.

To all whom t may concern.'

Be it known that I, JOHN BLAINER, a citizen of the United States, residing at Farrell, in the county of Mercer and State of Pennsylvania, have invented new and useful Improvements in Tool-Setting Gages, of which the following is a specification.

This invention relates to gages, and more particularly tothat class thereunder known as tool gages.

The primary object of this invention is the provision of a gage of this character, wherein a cutting edge tool may be properly gaged in order to ascertain whether or not the cutting edge thereof is in alinement with the aXis of the work.

To this end, use is made of a body, a level supported by the body and having a grooved head presenting parallel contact points primarily adapted for engagement with the work to determine whether or not the cutting edge of the tool is in perfect alinement with the axis of the work.

A further object of the invention is the provision of a device of the above stated character, and so constructed as to simplify this class of tool gages, increase their eiiiciency and durability, and adapting the same primarily for use in association with threading tools, turning too-ls, parting toolsv and for setting any other type of cutting edge tool when it is required that the point or cutting edge thereof should be at the same height as the aXis of the work.

With the above and other objects in view, the invention consists in the novel features, details of construction and combination of parts which will hereinafter be more fully .set forth, illustrated in'the accompanying drawing and pointed out in the appended claims.

Figure 1 is al side elevation illustrating the gage associated with a cutting tool and work;

Fig. 2 is a side elevation of the gage;

Fig. 3 is a top plan view;

Fig. 4 is an end view; and

Fig. 5 is a bottom plan view.

In carrying out the invention, and in order that a clear understanding of the same may be had, I have illustrated my improved tool gage 5 associated with the work 6 set up in the lathe and a cutting edge tool 7 i illustrated as being connected with the tool holder 8 of the lathe.

The improved tool gage illustrated generend walls 12 are formed by beveling the. same in an outward direction from the top face 13and from the base 14, as denoted by the character'l, and eachbeveled portion intersecting at the longitudinal center of the body portion to` provide contact points 16, while formed in the base or bottom face lll of thek body portion to opposite sides of its vertical center are notches 17 of dierent degrees, whereby the cutting edge of the various cutting tools may be inserted therein. In order to determine whether or not the cutting edge of the cutting tool 7, merely illustrative, is in proper alinement with the axis of the work, I provide a body 18 of T-shaped configuration. This body 18 is formed integral with the body portion 9, and at a point substantially medially of its length, including opposite laterally eX- ally by the reference character 5 is preferv stem, and the head 20 serving as the level, ex-

tending along the upper edge 13 of the body portion longitudinally thereof and of substantially a thickness equaling the thickness of the shank 19, that is to say, the material forming the head is of substantially elongated form and projects in opposite lateral directions beyond the flat side faces 10 and 11 of the body portion. The said head is provided with a V-shaped groove 21 extending throughout the length thereof, and providing a pair of spaced parallel contact points 22 adapted to engage with the work set up in the lath for determining whether or not the cutting edge of the tool is in alinement with the axis of the work. The shank 19 of the level is provided with a bore 23 in which the usual transparent receptacle holding the liquid is placed and the bore is closed through the medium of a threaded cap 24. The opposite side faces of the shank 19 are provided with the usual sight openings 25. The opposite end walls 12 and the base or bottom 14 of the body portion are beveled as indicated by the character 26 to present the same with a sharpened bottom and opposite end edges.

From the foregoing description, taken in connection with the accompanying drawing,

the advantages of construction and the rent to those skilled in the art to Which the invention relates, and While I have described the principles of operation of the invention, together With the device Which I now consider to be the best embodiment thereof, I desire to have it understood that the device shown is merely illustrative, and that such changes may be made When desired as are Within the scope of the appended claims.

I claim:

l. A tool gage comprising a body and a i'shaped level formed integral with said body, said body being formed in the base portion thereof With notches of different degrees arranged in a plane parallel With the level.

2. A tool gage comprising a body and a T-shaped level formed integral With said body having a grooved head presenting the head with spaced contact points, the said body having notches formed in the base portion thereof arranged in a plane parallel With the level.

3. A tool gage comprising a body portion, a T-shaped level formed integral with the body portion and having a grooved head extending longitudinally of the body portion.

4. A tool gage comprising a body portion, a T-shaped level formed integral With the body portion and having a grooved head extending longitudinally of the body portion7 and a shank extending transversely of the body portion.

In testimony whereof I aflix my signature.

JOHN BLAINER.
